Don’t rack your brain over what “Acama” might mean. Most likely it’s just a nonce word, coined by bureaucrats as a replacement for this roadway’s original 1911 name: Acacia Avenue. (They start with the same three letters, simple as that.) The City of Los Angeles annexed the SFV in 1915, forcing loads of Valley streets to be changed to avoid conflicts with those elsewhere in L.A. The Westlake neighborhood already had an Acacia Street in 1915, so this copycat was nixed. Ironically, Westlake’s Acacia was absorbed into 4th Street in 1931, but those bureaucrats saw no reason to change Acama back to Acacia.
